The present invention relates to new and useful improvements in windows and more particularly to novel awning type window assembly units constructed primarily from extruded elements and assembled'in a manner to permit ready removal of the tiltable vents and omission ofv the customary transversely extending vent division framing elements.

In recent years, theme of awning type-metal window assembly units has grownto tremendous volumes. This is. particularly true in home and apartment house usage where the awning type or horizontally hinged window vents have become popular because of the ability to vent the window'opening even in inclement weather without any appreciable danger of the rain entering through the vented opening in the absence of a driving wind. Windows of this type proposed in the prior art customarily employ vent framing elements extending transversely between the jar'nbs to provide intermediate sealing members and structural reinforcement. These prior art window assemblies also have customarily been furnished with non-removable tiltable vents necessitating original installationwith the vents un'glazed since the contractor normally is required to install: the assembly units in place to define the wall opening'and then build the remainder of the wall and building around them and is not willing to assume the disk and danger of breakage of the window glass. The result is that the unglazed vent framing and the transverse framing elements of the prior art window assemblies present inviting supports for scatfolding and walk boards and are used as ladder steps and are often damaged by such misuse. Also the vents thenn selves must be glazed after completion of the heavy construction by glaziers working either from ladders or from expensive outside scafiolding with their incident hazards to the workers.

Furthermore, the window units of the prior art, due to the transverse, framing elements and their hinge constructions, have'been limited in their angle of opening so that full advantage of the descending cool air, often present in warm and hot weather after the sun has set, cannot be effectively directed into the interior of the house or apartment building to more effectively cool the occupants. This limitation together with the non-removability of the prior art' window vents also poses a cleaning problem since the exterior of the glass pane cannot be etfec tively and conveniently washed except by standing on ladders or other support surfaces provided exteriorily of the f ulted States Patent C interconnected jamb, header and sillmembers and readily is to provide an awning type window assembly unit having the main framing elements and other structural parts formed principally from lengths of extruded shapes which may be made from aluminum or other suitable metals or materials, even plastic, and glazed vents unitarily mountable and removable from said main framing after the main framing has been secured in the wall opening and completion of the other building construction work likely to cause breakage of the glass panes;

Still another object of the present invention resides in providing an awning type window with pivots oliset towardthe'exterior face of the window main frame but within the confines of the main framing to provide a full 90 or better angle of opening when desired to take advantage of the descending cool air masses prevalent after sundown in warm weather.

:lA further object of the present invention is to form the main rectangular framing elements of a window unit of a novel cross-sectional configuration, namely, a channel-like element having an inner short wall section and an opposed outer long wall section extending respectively from the opposite edges of the connecting web section and provided adjacent their respective opposite ends with socket grooves along the opposed wall sections for respectively receiving inner and outer corner connectors and guide brackets for supporting conventional slide bars and housing suitable frame concealed window operating mechanism.

Still another important object of the present invention is to provide an awning window structure wherein the ventilators are individually removably secured to the frame or operating mechanism for the ventilators, whereby the ventilators may be field mounted to facilitate shop glazing of the ventilators. V

'=.A further object of the present invention is to provide an awning window structure wherein the. mounting means for the ventilators is adjustable to permit individual movement of a selected end of any ventilator to assure sealing contact with the adjacent frame element of the window structure although the frame may not be installed plumb and level.

Another object of the present invention is to provide an awning window structure with a novel and improved .g'eared operator which is extremely small and compact in structure and so designed as to be concealed and housed within one of the extruded jamb members of the main window frame.

A further object of the present invention is to provide an awning window including one or more ventilators which may be raised above the horizontal to facilitate increased ventilation and readily removed for ease of cleaning the ventilators.

Still another object of the present invention resides in the provision of ventilator units made up of opposed end and top and bottom extrusion bars of double channel form having opposed longitudinally extending rib elements defining socket grooves along one set of the opposed wall sections for receiving corner connectors.

A still further object of the present invention is to provide an awning window that is extremely neat and attractive in appearance, efiicient and durable in operation, inexpensive to manufacture and service, and otherwise well adapted for the purposes for which the same is intended.

Further objects will appear from the following description and appended claims when read in conjunction with the attached drawings wherein:

USCI'SJ Pin'tle' plates-56mm removably secured to the upper The? bars 28, 30 ,f-3 2;and 34 are each'formedjwithopposednlongitudinal corners ofthe ventilators 26"and support laterally out-v wardly extending pintle or hinge pins 60 that engage be tween the outer bifurcated ends of arms 62 fixed to the slide bars 54 by suitable screw fasteners 63 threaded into the slide bars. U-shaped holding dogs 64 pivotally carried by the pins 60 are adapted to coact with arms 62 to retain the pins 60 engaged with the arms 62. To this end-dogs 64 are arcuately slotted as indicated at 67 to partially encircle locking pins 66 removably threaded into registering apertures in the arms 62 and having enlarged heads to frictionally clamp dogs 64 against the inner faces of arms 62.

While plates 56 may be secured in any suitable manner to end frame elements 2830, they preferably'take the form shown in Figure 15. As there shown plate 56 comprises a main base portion spanningsocket grooves 36-38 of end frame elements 2830 and a pintle carrying portion of reduced width extending outwardly beyond the opposed ends of grooves 36-38 and extending parallel to the plane of grooves 36-38 in outwardly spaced overlying relation to corner joiner elements 40-empl0yed to connect the respective end frameelements to top frame element 32. Suitable screws 57 respectively passing through the base portion of plate 56 in position to re spectively thread into the main web of elements 28--30 and the respective corner joiners 40 secure plates 56 against movement with respect to frame elements 28-30 within the space between the opposed ribs.

The socket grooves 22 of the side members 12 and 14 slidably accommodate anchor plates 68 that support pivot pins 70 for the lower ends of hinge links or fulcrum arms 72. Clamp screws 74 pass through suitable apertures formed in the side members 12-14, extend through slots 76 in the plates 68 and thread into pressure strips or washers 78, which overlie plates 68 in the area of the space between grooves 22, to lock plates 68 in final adjusted position. This locking is effected bytightening screws 74 so as to draw the washers 78 againstthe plates 68 thereby causing the plates to bear against th'emain web of side members 1214 and lock the plates 68 in adjusted position. In this manner the pivot pins 70 may be selectively raised or lowered for a purpose later to be described.

The other ends of hinge links 72 are connected to anchor plates 80 slidably and adjustably engaged in the socket grooves 34 and 36 of ventilator side members 28 and 30. The plates 80 fixedly support pins or trunnions 82 that extend laterally from side members 28--30 and into suitable apertures in the upper ends of the hinge links 72. Peripheral grooves are formed in the outer ends of pins 82 to accommodate resilient C-clips 84 that retain the links 72 removably pivoted to pins 82.

A laterally extending torque shaft 86 positioned in the sill 18 has its opposite ends fixedly connected to torque shaft arms 88 which are connected by pitmans 90 to the lower ends of the slide bars 5 4 for raising and lowering bars 54 and closing and opening ventilators 26 in unison. Rotational movement is imparted to shaft 86 by a novel operator mechanism carried by a sectional journal box or housing 92 suitably secured in the lower end of one of the side members 12 or 14. This housing, preferably formed from a novelly shaped extrusion, houses a gear segment 94 fixedly secured to shaft 86 and meshingly engaging a worm gear 96 rotatably supported in the hous-.

ing. The rear end of worm gear 96 terminates in a cylindrical extension 98 protruding through'the interior face of the selected side member which extension is held within the socketed end of removable operating crank handle 100 by a set screw 102. a

While any suitable means may be employed to fixedly connect shaft 86 to arms 88 and'gear segment 94, arms 88 and segment 94 are preferably provided with multisided openings that receive related portions of a multisided torque shaft 86 which passes freely through an engearsegment 94 is rotated by worm gear 96, the torque shaft and its connected arms 88 will also be rotated to impart through pitmans a vertical sliding movement to the slide bars for raising or loweringthe ventilators.

Referring for the moment specifically to Figure 4, it will be noted that pivot pin 60 is disposed forwardly of the longitudinal axis of slide bar 54 whereas pivot pin 70 is disposed rearwardly of the longitudinal axis of slide bar 54. As a result of this relationship, the pivot pins 60, 70 and 82 define what is commonly known in the art as a balancing and locking triangle. Accordingly the ventilators 26 are properly balanced and pivotally connected to the operating mechanism to permit convenient opening of the ventilators and subsequent closing of the ventilators against the side members.

The location of pivot pin 60 as illustrated also permits the ventilators 26 to be raised above the horizon or a plane perpendicular to the side members 12 and 14 without the upper edges of the ventilators 26 binding against the side members 12 and 14. Thus it will be apparent that the ventilators themselves may be positioned to serve as deflectors for directing descending cool air into a room equipped with the novel window structure of this invention and to aid removal of hot air from the ceiling area.

It has heretofore been explained that slide plates 68 are vertically adjustable for the purpose of selectively raising or lowering the pivot pins 70. This adjustment is necessitated due to the fact that frequently a selected end of a selected ventilator may not fit tightly against one of the side members because of incorrect installation of the frame 10 or extrusion tolerances varying in the various ventilator and frame forming members. Therefore, the simple and practical method thus utilized in the present invention for maintaining the pivot 70 in a vertically adjusted position expedites the proper alignment of the ventilators to overcome this trouble if and when it arises.

Referring now to Figure 14, it will be seen that clamp screws 66 for securing pintle plates 56 to their respective support arms 62 are readily accessible to a person standing in a room equipped with the window of this application. Consequently, removal of the ventilators can be readily effected by loosening the opposite screws 66 to release the opposed holding dogs 64, then rotating the respective dogs on their pivot pins to free the dogs from their clamp screws 66, and finally removing the resilient Cclips 84 from pivot pins 82 and bowing one or the other of the hinge links 72 outwardly to disassociate it from its associated hinge pin thereby freeing the window at one end so as to permit it to be tilted inwardly toward the interior of the room and withdrawn from its other hinge link 72. It should be noted that this removal process assures a positive support for the ventilator right up to the time that positive action is taken to how one of As a consequence,

the hinge links to free the ventilator. accidental disassociation of the ventilator in installing and removing it is adequately safeguarded.

It will further be apparent that the window unit of this invention may be properly adjusted for operation at the factory so that installation of the unit on the job may bereadily effected with the ventilators appro priately marked, removed and all linkage turned to a position within the confines of the main framing to guard against accidental damage. Removal of the crank handle will assure that no one will inadvertently expose any linkage for possible damage and removal of the ventilators will positively prevent use of the unit as a ladder or a scaffold board support.

To assure proper journalling and slidability of the various parts all points where metal to metal contact between relatively movable parts occurs are provided with Teflon, nylon or similar self lubricating bushings or slide pads to prevent galling and corrosion of the parts due to electrolytic action.
